Eubranchus farrani from the Mediterranean sea?

July 4, 2007
From: Sylvie Grall

Dear Bill,
I found this seaslug in very shallow water on Zostera noltii in the Etang de Thau close to Sète. This is a first and unique sighting (no other specimen on the same dive and I'ven't seen it again since then). I didn't see any hydroids close by.

Locality: Etang de Thau, 2 m, France, Saltwater lake, 14 April 2007, Seagrass (Zostera noltii) on mud. Length: under 3 cm. Photographer: Sylvie Grall.

Could you or anyone help me identify it?
Thank you very much.
Sylvie.

Dear Sylvie,
I am not an expert on the Mediterranean fauna but I am pretty sure this is a dark form of Eubranchus farrani. The shape of the cerata and whitish network on the cerata match other photos and in the close-up [lower left] I can see orange patches on the back, which is characteristic of the species.

Best wishes,
Bill Rudman
